To all whom it may concern:

Be it known that I, ARTHUR L. REMING- TON, a citizen of the United States, residing at Worcester, in the county of Worcester and Commonwealth of Massachusetts, have invented a new and useful Improvement in a Machlne for Forming Yarn Packages, of

which'the following, together with the accompanying drawings, is a specification.

My. invention relates to machines for winding yarns, and has for its object to provide an improved mechanism that is adapted to form yarn into independent packages of such size that the yarn may later be conveniently wound on bobbins or filling carriers, or the packages may be used in various color combinations'to constitute a Warp in weaving.

A further object of my invention is to adapt my improved mechanism for use in connection with an inspection frame on which the yarn may be conveniently eXamined in order to permit the removal of all imperfections therefrom before forming it into packages. Further advantageous features of my'invention will hereinafter more fully appear, reference being had to the accompanying drawings in which,

Referring to Figs. 1 and 2, my invention is shown, for the purpose of illustration, in connection with an inspection frame 1 which provides inclined side-members 2, between which are rotatablymounted a number of spaced shafts 3. Each shaft 3 is provided atone end with a bevel gear 1 in mesh with a pinion 5 mounted on a shaft 6, extending sectional view the length of the frame 1, parallel to one of the side members 2. The shaft 6 is adapted to be driven "f om a su ta le s urced 31 s idable' power, not shown. A cylinder 7 having a frictional surface is mounted on each of the shafts 3 and one of my improved winding mechanisms is adapted to cooperate with each of the cylinders 7, as will 'now be described.

As best shown in Fig. 3, a pair of vertical standards 8 are secured to the side members 2 at opposite points on the frame 1, ad:

. periphery of the cylinder 7 A pressure roll 12 is supported at its ends in slide blocks 13, each of which is provided with a tongue 13 received in a slot 9 of one of the standards 8, as best shown in Fig. 6. A traversing bar 14 is slidably supported near its ends on the blocks 13by means of bolts 15 received in slots 16. The traversing bar 14 is provided along its lower edge with a plurality of spaced notches 17, the distance between adjacent notches being substantially the same as the distance between the center lines of adjacent yarn carriers 11. The bar 14' is adapted to receive a longitudinal reciprocatory movement, as will now be described.

As best shown in Fig. 3,the right hand end of the shaft 3, supporting the cylinder 7, is provided with a gear 18 which is in mesh with apinion 19 mounted on a countershaft 20, extending substantially parallel to the shaft 3. A cam 21 provided with a groove 22 is carried on the shaft 20, and a lever 23 is provided at its end with a roller 24 received in the groove 22. The lever23 is pivotally supported at a point intermediate its ends on a stud 25 which is received in a slot 23, for the purpose of adjustment, and the upper end of the lever 23 is pivotally connected to a cross head 26, by means of a pin 27. The cross head 26 is slidably sup .ported betweenguides 28 secured to one of the standards'8. The cross head 26 has se- 29, the lower end of which is connected to the'traversing bar 14 by means of a link 30. The link 30 is pivotally connected to a block in slot in a m 29. R W 7 p tion of the, shaft 3 will cause a vibratory movement of the lever 23 by reason of its connection to the cam 21, and this movement of the lever 23 will in turn be translated into reciprocatory movement ofthe travers ing bar l t, by reason of its rigid connection with the cross head 26.

WVhile only one complete traversing mechanism is shown mounted on the frame 1, in Fig. 1, my invention contemplates the provision of a travers'ng mechanism operating in connection with each of the cylinders 7Q When it is desired to operate the machine the several strands of yarn 33 are taken fromv a suitable. creel, not shown, are passed under roll 3 and are passed over rolls} 35 and 36 above the frame; The. yarn is then passed downwardly around a roll 37, from which it passes upwardly to anumber of spaced. rolls 38 rotatably supported; one above the other. The separate sets of-ithreads passing over. each roll. 38 are then led to the traversing mechanisms, described. above,- each. separate thread passing through a feeler 39,. pivotally mounted on a shaft 40, extending betweenthe standards 8 above the traversing, members 14; lVhen a thread is passing through a feeler 39 it is held in a slightly elevated position, as shown in Fig. 5, but should the thread break, the other end of the feeler 39 will be allowed to fall, thereby completing the electric circuit of a signal bell through a contact 4:1, which circuit is normally open when the feeler is depressed by the passage of thread therethrough. The exact formof the feelers 39 form no part of the present invention and obviously other types of feelers or detectors may be employed.

Each thread extends froma feeler 39 into one of the notches 17 on'thc. traversing bar 141- from*w-hence it passes to a yarn carrier 11. Each thread is held in close contact with its yarn carrierhy the roll 12 which is adapted to exert considerable pressure on the threads, by reason of the fact that'the weight of the traversingibar is entirely sup; ported by the roll 12. The several package carriers 11 are in turn held in closeengage ment' with the cylinder 7.

hen the machine isoperating, rotation of the cylinders 7 will cause the yarn carriers 11 to rotate therewith, which in turn will cause the threads to be woundon the carriers 11. At the sametime, rotation=of the shafts 3 will also cause a reciprocatory movement of the traversing: bars 14, so that the threads passingtlrrough the notches17 will be laid on the carriers 11- with a traversinghmove' ment, thereby bu ldingzup yarnpackages on the: carriers that are nearly equal to the width of. thecarriers: Ass-thread issnroved back. and; forth onva carrier,i-tl1"e pressure exerted by thezroll: 12 M111 compressithe yarn on the carriers 11 and will serve to maintain the yarn. in the position in which it is laid by the movement of the traversing bar 1 1. As the yarn packages increase in diameter, the roll 12 is free to move upwardly between the Standard 8, carrying the traversing bar 14: therewith, this upward movement of the bar 14 being permitted by reason of its slid ing connection with the arm 29 through the link 30 andblock 31. The traversing movement of bar 14 may be adjusted by shifting an arm 25 which carries the stud 25, there'- by varying the length of the arm through whichthe lever 23 acts on the cross head 26.

From the foregoing, it is apparent that I have provided a yarn winding machine that is particularly adapted to form separate yarn. packages which may be readily removed from the shaft 10 and placed in a filling, winder for transferring the. yarn to bobbins or filling, carriers, or may be used in various colorcombinations for a warp. Obviously, the diameterand width of the packages oan be controlled asdesired, in order to obtain the proper amount of yarn on each carrier 11.

My improved compressing mechanism is particularly adapted for use in connection with an inspection frame, of the type shown in Fig. 1, in which the threads are open for thorough examination asthe-y pass over the frame from the creek-therebyalfording ample opportunity to remove allimperfections, such as slubs, bad pieces, hard and slack twists, and other defects which are liable to occur in the yarn.

While I have shown my invention in connection with a particular type of inspection frame, it is not so limited, but is capable of being applied-to other types of frames without departing; frommy invention, which is only subject to such limitations as may come within the scope of the appended claimsi Iclaim 1., In aimachineof the class described, the combination with a rotating shaft having a: pluralityof yarn carriers mounted thereon, of a member adapted to lead yarn to eaclr of said carriers, and means for imparting a traversing movement to said member to form: a separate yarn package on each carrier, the said memberv being attached to slides cooperating with guides, and adapted to be moved 1 directly away from the center of said yarn carriers by the building of yarn on said carriers.
